(Whiteboard: [MemShrink:P3])

I haven't experimentally verified this leak, but I'm pretty sure it happens. BrowserElementParent.jsm keeps a list of outstanding DOMRequests. If a frame crashes while it has an outstanding DOMRequest, we'll never release the request. This is bad, because we should fire onfailure. But it's worse because the request holds a reference to the owner of the frame that just died, so we'll permanently leak that window (I think).
